内燃机的控制装置
摘要：
本发明提供一种内燃机的控制装置，能够抑制气缸间的内部EGR量的不均，从而能够提高商品性。内燃机(3)的控制装置(1)包括ECU(2)，内燃机(3)具有电动涡轮增压器(5)与1号气缸(#1)～4号气缸(#4)。ECU(2)根据内燃机(3)的运转状态，对应于各气缸来设定电动涡轮增压器(5)的涡轮(5b)的目标旋转变化量(DN#i)(步骤35)，且在包含各气缸的一个燃烧循环中的排气行程的控制期间中，对电动涡轮增压器(5)的TC马达(5c)进行控制(步骤23)，以达到所述目标旋转变化量(DN#i)。
摘要（英）：

Provided is a control device of an internal combustion engine for suppressing variation in the internal EGR amount among cylinders and improving the merchantability. A control device (1) of an internal combustion engine (3) has an ECU (2), wherein the internal combustion engine (3) includes an electric turbocharger (5) and first to fourth cylinders (#1 to #4). The ECU (2) sets a target rotation change amount (DN#i) for a turbine (5b) of the electric turbocharger (5) corresponding to each cylinder according to the operation state of the internal combustion engine (3) (Step 35), and controls a TC motor (5c) of the electric turbocharger (5) in a control period, which includes an exhaust stroke in one combustion cycle of each cylinder, to match the target rotation change amount (DN#i) (Step 23).
